It seems like your gallery image code for variation doesnt do something right. I’ve checked all my limitation on the server, it works fine with woocommerce, it can handle over 500 variations with easy.

Let me explayn again the issue:

I can add all the variables that i want in wocommerce, i can save as many images i want for each variations, check the management stock, etc. and all fo that informations are saved corectly in database.

The problem appears in fron end, something messes things up there.

I’ve installed this plugin:

And it works great. That will only solve my image gallery problem, but wont solve the disable grey out of stock (or variations that doesnt exist). And of course it’s another image gallery … changes my product design, i dont like that :))
